Warning: %Email message% is a corrupt file. The file cannot verify
Unable to backup the attachment data associated with one or more messages. Some messages and their attachments may have been deleted while the backup was already in progress.
If the issue still occurs after performing the steps above, the registry can be modified per the following steps, to prevent jobs from failing on files which Backup Exec believes to be corrupt:
Warning: Use of this registry key will result in the successful status of job operations that otherwise would have qualified as being failed operations. Ordinarily, successful job status indicates that 100% of the targeted data has been protected and recorded to media. After this registry key has been enabled, a successful job status will indicate a primarily successful backup operation with exceptions. When this key has been enabled, Symantec recommends that an inspection of job log files is performed to make note of any possible exceptions that may have occurred during a backup operation.
Warning: Incorrect use of the Windows registry editor can have disastrous results on a server operating system. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.
